FRANK BURY, 0F LYNDORA, PENNSYLVANTA, ASSIGNOR 0F ONE-HALF TO JOSEPH A.KALINA, OF LYNDORA, PENNSYLVANIA.

TROLLEY.

To all whom it may concern:

Be it known that I, FRANK BURY, a subject of the Emperor ofAustria-Hungary, residing at Lyndora, in the county of Butler and Stateof Pennsylvania, have invented certain new and useful Improvements inTrolleys, of which the following is a specification, reference being hadtherein to the accompanying drawing.

This invention relates to trolleys, and the objects of my invention areto furnish a trolley harp with positive and reliable means, as willhereinafter appear, for retaining the trolley wheel of the harp upon thetrolley wire, or electric conductor, and to provide a trolley harp thatcan be used in connection with various types of trolley poles,especially the poles of high speed, suburban electric trolley railways.

Further objects of my invention are to provide a trolley attachment thatwill prevent the accidental displacement of the trolley wheel whenpassing around a short curve, descending a grade, or encountering wireirregularities, or the overhead construction of a trolley system, and toaccomplish the above results by a mechanical construction that issimple, durable and highly efficient for the purposes for which it isintended.

With the above and other objects in view, the invention resides in thenovel construction, combination and arrangement of parts, to behereinafter specifically described and then claimed. a

Reference will now be had to the drawing, wherein there is illustrated apreferred embodiment of the invention, but it is to be understood thatthe structural elements are susceptible to such variations andmodifications as fall within the scope of the appended claims.

In the drawing :Figure 1 is a side elevation of the trolley inaccordance with this invention. Fig. 2 is a plan of the same. Fig. 3 isan end view of the trolley, and Fig. 4 is an enlarged vertical sectionalview of one of the rollers or spools of the trolley.

The reference numeral 1 denotes a portion of the trolley pole, havingthe upper end thereof enlarged and bifurcated to provide a slot andoppositively disposed apertured arms 3, and in these arms there ismounted a transverse pivot pin 4. Pivotally mounted Specification ofLetters Patent.

Application filed March 14, 1912.

Patented Aug. 2'7, 1912. Serial No. 683,909.

upon this pin is the apertured tongue 5, of a harp 6, said harp havingapertured arms 7 for the j ournaled pin 8 of a trolley wheel 9, adaptedto travel upon a wire 10, or other electric conductor.

With the harp pivotally connected to the upper end of the pole, thetrolley wheel 9 can easily adjust itself to the wire, particularly upona curved section of said wire, thereby compensating for any inequalitybe tween the track beneath the trolley wire and the correct position ofsaid wire relatively to the track.

The harp 6, adjacent to the lower end thereof, is provided with a set ofbearings 11, having the upper ends thereof bifurcated or slotted as at12, to provide lugs, which are apertured to receive pivot pins 14.Pivotally mounted upon the pins 14 are the lower end 15 of arms 16. Theupper ends of the arms are constructed similar to the upper ends of thebearings 11, whereby roller or spool holders 17, can be pivotallyconnected to the upper ends of the arms 16 by pins 18. The pivotalconnection;- of the holders 17 are at right angles to the p otalconnections between the arms 16 and the bearings 11, whereby the holderswill have a movement longitudinally of the trolley, and the arms 16 andoutward or transverse movement with respect to the trolley. The holders17 are provided with stems 19 and revolubly mounted upon the stems arerollers or spools 20, retained upon the stems by cotter pins 21. Theholders 17 are limited in their movement by the shoulders 22 of saidholders, engaging the shoulders 23 of the arms 16, and said holders arenormally retained in a vertical position by fiat springs 24, secured tothe sides of the arms 16, and engaging the sides of the holders 17 Thearms 16 are normally retained in a vertical position by fiat springs 25,secured to the outer sides of the bearings 11, and engaging the outersides of the arms 16. In order that the arms 16 can be sprung outwardly,the lower pivoted ends of the arms have outwardly projecting aperturedlugs 26, to which are connected the upper ends of branch cables 27 saidcables passing through eyelets or staples 28, carried by the harps 6,and connecting with the main cable 29, that extends downwardly to thecar, whereby the conductor or operator of the car pivoted can easilypull upon the cable to open the arms 16, and remove the rollers orspools 20 from their juxtaposition to the trolley. wire 10. p I

To facilitate the lowering of the'trolley pole, said pole has anadditional cable attached to the pole, contiguous to the upper endthereof.

In the operation of'the'trolley, the rollers or spools preventaccidental displacement of the trolley wheel 9, relatively to the wire-10,- but these'rollers orspools recede when any obstruction isencountered, as a-wire hanger or rail.

'VVhat I claim is 1. The combination with a--tr0lley pole, aj harppivotally connected to sai'd'pole, and a wheel journaled in said harp,and adapted totravel upon the trolley wire, of bearings carried by saidharp, arms pivotally mount-Q ed in the upper ends of saidbearings,hold-' ers pivotally connectedto the upper ends of; said arms,spools revolubly supported by said holders in proximity to the wire uponwhich said wheel travels, lugs carried by by said bearings andarmszinalinement by :said :arms and adapted said arms, :branch cablesconnected 1 to said lugs, whereby said arms can be swung outwardly, andmeans carried by said bearings adapted to normally maintain'said armsinalinement with said bearings.

,2. In a trolley, a pole, a harp pivotally connected to said pole,bearings carried by said harp arms pivotally connected to said bearings,holders pivotally connected to said arms on pivots-at=right angles tothe pivotal connections of said arms, spools revoluloly supported bysaid holders, springs-carried adapted to iretain said therewith, springscarried :to' retain said holders in a verticaLposition, and-meansattached to said arms and adapted to ifacilitate theoperiing of saidarms -fto separate such spools.

In testimony whereof I' aflix my'signature in the presenceofttwowitnesses.
